Discovery Krypton was discovered in 1898 by Sir William Ramsey, a Scottish chemist, and Morris Travers, an English chemist. Krypton was found by examining residue left after almost all of the components in liquid air.
Location Krypton can be found in hot springs, volcanoes and in the air. About .0001% of the Earth's atmosphere is krypton. AppearanceKrypton is a colourless, odorless gas that is nonreactive to other elements. However, when a current of electricity is sent through a container that contains low pressure krypton, the krypton glows a smokey-white. Interesting Facts Krypton is also the name of Superman's destroyed home planet. The planet Krypton is depicted in numerous Superman comics, movies, and TV shows.
